AB  - With  currently  existing  fast  magnetic  resonance  imaging  (MRI)  techniques,  it  is  possible  to  evaluate  for  shunt  malfunction  in  less  than  90  seconds.CT  findings  of  ischemic  stroke  lag  far  behind  diffusion-weighted  MRI  findings,  which  can  detect  edema  within  the  first  hour  after  the  event.MRI  is  the  imaging  modality  recommended  by  the  American  College  of  Radiology  for  identifying  appendicitis  in  pregnant  patients  who  have  a  nondiagnostic  ultrasound.Whole-body  MRI  is  used  in  metastatic  cancer  staging  and  has  a  higher  sensitivity  and  specificity  over  scintigraphy  in  this  application.  Image  acquisition  times  of  30  to  45  minutes  are  similar.3.0T  magnets  are  becoming  more  widely  available  and  provide  thinner-slice,  higher-resolution  images  in  a  shorter  amount  of  time  than  the  current  standard  1.5T  magnet  machines.
